In infinispan-4.1.0.CR3,while starting Hotrod server - Found Log4j initialization errors

savin7 Aug 26, 2010 6:45 AM

Dear All,

I have taken the latest distribution infinispan-4.1.0.CR3 and started the Hotrod Server using the below command

D:\Infinispan\infinispan-4.1.0.CR3-all\infinispan-4.1.0.CR3\bin>startServer -c ../etc/config-samples/minimal.xml -r hotrod

Then I got the Log4j not properly initialized below errors in the server console. [but the server is started and working fine]

log4j:WARN No appenders could be found for logger (org.infinispan.server.core.Main$).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

I have changed the minimal.xml in the etc\config-samples folder and commented the root appender File in the log4j.xml, uncommented the root appender CONSOLE

</root>

Please let me know, How can I get around this error in distribution infinispan-4.1.0.CR3 and make the server logging work fine ?????

Attached are my minimal.xml and log4j.xml.

Kindly do the needful.

Thanks & Regards,

Savin

minimal.xml 1.4 KB
log4j.xml 2.3 KB

I don't have a Windows machine around, but works fine on Unix. In startServer.bat, there's a log4.configuration property like:

-Dlog4j.configuration=..\etc\log4j.xml

That should in theory work. Alternatively, try: -Dlog4j.configuration=file:/c:/path/to/log4j.xml

Btw, this is not an error, just a warning

Dear Galder,

Thanks - after modifying "file:/D:/full/path/log4j.xml" in the -Dlog4j.configuration of startServer.bat. It can able to detect the log4j.xml.

I do agree its a warning not a error my apologies for the same.

One small out of box question, Even If I gave the full relative path 'D:/full/path/log4j.xml' without 'file:/', its not able to pick up the log4j.xml file. Any reasons why we have to give file:/ in specific ? If time permits, Kindly let me know ??

Thanks & Regards,

Tbh, I have no idea. I had a note from my Windows days on what logj4.configuration should look like.

Btw, can you try the following? -Dlog4j.configuration=file:/../etc/log4j.xml

Dear Galder,

As you have suggested, I have changed it to -Dlog4j.configuration=file:/../etc/log4j.xml but still it couldn't able to find the file path and results in below exception. For your inference I have pasted the exception below.

i tried using -Dlog4j.configuration=file:/c:/path/to/log4j.xml by saying i am starting a hotrod server startserver -r hotrod -p 19733 -Dlog4j.configuration=file:/c:/path/to/log4j.xml
the log4j.xml file exists at that path but still i get the

dan.berindei Jul 25, 2012 7:24 AM (in response to adityalele)

Aditya, make sure you replace the -Dlog4j.configuration value in startServer.bat. If you pass it as a command-line argument to startServer.bat, it will be considered a parameter of the Main class (and it will be ignored).

@Dan, it shouldn't be ignored, see: https://github.com/infinispan/infinispan/blob/master/server/core/src/main/scala/org/infinispan/server/core/Main.scala#L235

Hmmm, unless logging resolution happens before that line. @Aditya, defo worth a try to @Dan's suggestion.

Adding "-Dlog4j.debug" to the script should tell us more about how log4j boots - mind give it a try and post everything log4j outputs to the console?

Aditya, you need to modify the script itself, not pass it as an argument.

This should be solved in the next 5.2 infinispan release. You can also find a workaround for this problem here: https://issues.jboss.org/browse/ISPN-2180
